Copeland Comfort Control (White Rodgers) 90-T75C3 Transformer

The White Rodgers 90-T75C3 Transformer is a heavy-duty, 75VA Class 2 control transformer engineered for reliable 24V secondary power in demanding HVACR applications. Designed with a multi-voltage primary (120/208/240V), this foot-mount transformer provides the versatility needed for various field installations, serving as the direct replacement for Y66T13-0. The open construction design facilitates efficient heat dissipation, while the integrated manual reset circuit breaker ensures critical protection against secondary overloads or short circuits, preventing costly damage to downstream components like contactors and control boards.

• Universal Compatibility: Multi-tap primary winding supports 120V, 208V, and 240V inputs for streamlined inventory.
• Integrated Protection: Features a manual reset breaker to safeguard the 24V circuit without needing external fuses.
• High Power Output: Delivers 75VA of power, sufficient for handling multiple solenoids and high-draw relays.
• Direct Retrofit: Exact footprint and performance specifications to replace Y66T13-0 and JARD 7541C seamlessly.
• Extended Durability: 11-inch color-coded wire leads and robust foot mounting withstand high-vibration environments.

Common Questions

What is the maximum amperage output of the 90-T75C3?
This 75VA transformer provides approximately 3.125 Amps at the 24VAC secondary terminal.

Can I use this to replace a 40VA transformer?
Yes, as long as the voltage ratings match, a 75VA transformer can replace a lower VA unit, providing more "headroom" for the control circuit.

How do I reset the unit if it trips?
Locate the integral circuit breaker button on the side of the housing. Ensure the fault is cleared before depressing the reset button.
